Computer Freezes While Playing Sims 4

Do you have any programs running in the background when you play The Sims? Especially graphics programs, such as those used for screenshots.
Close all such programs that you do not need to use during the game.
Check if your Windows is up to date

Perform a clean boot of your computer

By the way, you can also check whether your system has any problems that may not have been shown in DxDiag

However, the most likely cause is some program running in the background what conflicts with the game.
Of course, the reason can also be very simple. Poor ventilation, because the computer was not cleaned for a long time, can also give such an effect.

I don't work for EA

I am not aware of any programs running in the background but it wouldn't be the first time I've forgotten to close one. Definitely need to blow the dust out of my computer for sure. I will try that first, but if it continues I guess I'll have to do a clean install of windows.
